Introduction
GEU-0520 and GEU-0820 are members of LevelOne
Unmanaged Switch 2 series which are powerful,
high-performance Gigabit Ethernet switches. With 5 or 8
ports capable of 10/100/1000 Mbps auto-negotiation
operation (NWay), the switch could automatically
negotiate with the connected partners on the network
speed and duplex mode. It is ideal for micro-segmenting
large networks into smaller, connected subnets for
improved performance, enabling the bandwidth
demanding multimedia and imaging applications.
Moreover, the 10/100/1000Mbps auto-sensing ability
provides an easy way to migrate 10/100Mbps to
1000Mbps network. Compared to the shared 10Mbps or
100Mbps networks, the switch delivers a dedicated
10/100/1000Mbps connection to every attached client
without bandwidth congestion issue. This switch also
supports auto MDI/ MDI-X function. Each port could be
used to connect to another switch or hub without
crossover RJ-45 cable.
Store-and-forward switching mode promises the low
latency plus eliminates all the network errors, including
runt and CRC error packets. To work under full-duplex
mode, transmission and reception of the frames can
occur simultaneously without causing collisions as well as
double the network bandwidth. Moreover, Pre-IEEE
802.3az Energy Efficient Ethernet is supported to save
power consumption
GEU-0520 and GEU-0820 are plug and play without any
software to configure and also fully compliant with all
kinds of network protocols.

Quick Installation Guide
This section provides unpacking and setup information for
the Switch.
Unpacking
Open the shipping carton and carefully unpack its contents.
The carton should contain the following items:
One GEU-0520, or GEU-0820 Gigabit Ethernet Switch
Four rubber feet with adhesive backing
Wall-mount Kit
One external power adapter
QIG Manual
If any item is found missing or damaged, contact your local
dealer for a service.
Installation
The site where you install the Switch stack may affect its
performance. Use the following guidelines when installing
the switch:
Install the Switch in a cool and dry place. See
specifications for the acceptable temperature and
humidity operating ranges.
Install the Switch in a site free from strong
electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
Leave at least 10 cm of space at the front and rear of the
hub for ventilation.
Install the Switch on a sturdy, level surface that can
support its weight. When installing the Switch on a level
surface, attach the rubber feet to the bottom of each
device. The rubber feet cushion the hub and protect the
hub case from scratching.

Wall Mounting
Before you begin, you need 2 wallboard screws to mount
the unmanaged switch.
To mount the unmanaged switch to the wall:
1. Determine where you want to mount the unmanaged
switch. Verify that the surface is smooth, flat, dry, and
sturdy.
2. Drill two pilot holes into the wall surface. The
wall-mount slots are two crisscross slots on the bottom
panel of the unmanaged switch.
3. Insert a screw into each hole, leaving a gap between the
surface and the base of the screw head of at least 0.1
inches (3 mm).
4. Place the unmanaged switch wall-mount slots over the
screws and slide the unmanaged switch down until the
screws fit snugly into the wall-mount slots.
5. Connect the unmanaged switch to the other devices, as
described in the “Connecting the Equipment” section.
Flat Surface Installation
To deploy the device on a desktop or other flat surface:
1. Place the unmanaged switch on a desktop near an AC
power source.
2. Connect the unmanaged switch to the other devices, as
described in the “Connecting the Equipment” section.
Connecting the Equipment
This section describes the process for connecting the
device to the network.
1. Power down all of the devices you want to connect to
the switch.

6
2. Connect the Ethernet cable to the Ethernet port of a PC,
printer, network storage, or other network device.
NOTE We recommend using Cat5e or better cable.
Also, do not exceed the maximum cabling distance of 328
feet (100 meters) per segment.
For cable selection, refer to the following table：
Network Speed Cable Type Max. Length
10Mbps Cat. 3, 4, 5 UTP/STP 100 meters
100Mbps Cat. 5 UTP/STP 100 meters
1000Mbps Category 5e, 6 UTP/STP 100 meters
3. Connect the other end of the network Ethernet cable to
one of the numbered unmanaged switch Ethernet ports.
4. Repeat Step 2 and Step 3 for each device you want to
connect to the unmanaged switch.
CAUTION Make sure you use the power adapter
included with the switch. Using a different power adapter
might damage the switch.
5. Connect the power adapter to the power port on the
back panel of the unmanaged switch.
6. Power up the devices connected to the switch.

Magnet Mounting
This model support magnet mounting
Introduction to magnetic mounting parts
There are two permanent magnets in the bottom of switch,
as shown in below figures.
GEU-0520
GEU-0820
Installation procedure
Attach the magnet-mounted device to the specified
location. Take care not to get your fingers stuck between
because the magnetism is very huge.

CAUTION
Select the installation location carefully. In the case of
poor surface, magnet mounting may not be reliable.
Put the device at a stable place free from vibrations or
shocks. Otherwise, personal injuries or equipment
damage may occur.
Avoid installing the device at a high place because
personal injuries or equipment damage may occur in
case of a falloff.
Avoid frequently moving the desk-mounted device
because such movements may damage the surface
coating.
Keep the front panel of the device facing upwards and
the two sides with ventilation holes vertical to the
ground, if you want to install the device vertically.
Pay attention that the weight of external cables should
not bring about a falloff, which may result in personal
injuries or equipment damage.
Keep floppy disks and magnetic cards away from
magnets to avoid erasure of any information.
Keep computers and monitors that are easily influenced
by magnetic fields away from magnets. Otherwise, faults
may occur to these electronic devices.
Power On
Plug one end of theca power adapter into the power
connector on the switch and the other end into the local
power source outlet.
After the switch is turned on, the LED indicators will
momentarily blink, showing a reset of the system.
